FAQs For Overmolding Services

overmolding faq
What is overmolding?

Overmolding is a process where two or more materials are combined to create a single part. It involves molding a layer of material over a previously molded part to add functionality, durability or aesthetic appeal.

What materials can be used for overmolding?

Overmolding can be done with a variety of materials, including plastics, rubbers, metals, and more. At Firstmold, we use a range of thermoplastics and thermoset materials for overmolding.

What are the benefits of overmolding?

Overmolding can add a variety of benefits to a part, including improved functionality, better grip, increased durability, and aesthetic appeal. It can also reduce the need for additional assembly steps and minimize the number of parts needed.

What types of parts are suitable for overmolding?

Overmolding is commonly used for parts that require added functionality, such as handles, grips, seals, and buttons. It is also used for parts that require protection or insulation, such as electronic components.

How does overmolding differ from two-shot molding?

Overmolding involves molding a layer of material over a previously molded part, while two-shot molding involves molding two different materials simultaneously into a single part. Overmolding is typically used for parts with simpler geometries, while two-shot molding is used for more complex parts.

How can I ensure the quality of overmolded parts?

At Firstmold, we have a rigorous quality control process in place to ensure the highest standards of quality. We use advanced equipment and techniques to test and verify the integrity of each part, and we work closely with our clients to ensure their specifications are met.
